BACKGROUND OF THE INVENTION

1. Field of the Invention

The present disclosure relates to a method, apparatus, and computer-readable medium for quilting. The present disclosure more specifically relates to a method, apparatus, and computer-readable medium for a braking system in a quilting apparatus.

2. Description of Related Art

Machine quilting is quilting made through the use of a sewing machine to stitch rows or patterns using select techniques to stitch through layers of fabric and batting in the manner of old-style hand-quilting.

Free motion quilting is a process used to stitch the layers of a quilt together. Longarm quilting involves placing the layers to be quilted on a special frame. The frame has spindles on which the layers are rolled, keeping these layers together without the need for tacking or pinning. These frames are used with a sewing head mounted on a moveable platform. The platform rides along tracks so that the sewing head can move across the layers on the frame.

In all of the free motion quilting configurations the user of the quilting machine determines when and where to stop the movement of the sewing head of the quilting machine and then to move the sewing head of the quilting machine in a different direction.

DETAILED DESCRIPTION OF THE INVENTION

In free motion quilting, the user freely determines the location and movement of a sewing head of a quilting machine relative to a work piece. The user moves the sewing head of the quilting machine along X-Y axes over a textile retention area. In computer driven or computer programmed quilting, the user selects the movement of the sewing head, and the computer drives or moves the sewing head based on the user inputs. However, a user often does not always quilt in continuous fluid motions. Rather, a user often has to stop the movement of the sewing head of the quilting machine from moving in one direction and then initiates movement of the sewing head of the quilting machine in another direction.

Additionally, in free motion quilting, a user will sometimes intend to quilt in straight lines either along the X-axis or along the Y-axis of the textile retention area. In this situation, ideally, the quilter will be able to prohibit the sewing head from moving along the unintended axis such that the sewing head only moves along the intended axis of stitching.

Exemplary embodiments of the present disclosure provide a method, apparatus, and computer-readable medium that allow a user to quickly stop movement of the sewing head of the quilting machine, whereas subsequent motion can be in the same or different direction. Exemplary embodiments of the present disclosure also provide a means for a user to move a sewing head of a quilting machine along either of a pair of orthogonal axes without deviating from the desired axis of stitching. Exemplary embodiments of the present disclosure further provide a computer driven or computer programmed quilting machine that can more efficiently stop movement of the sewing head in one direction and then move the sewing head in the same or different direction.

Referring to FIG. 1, a quilting machine 100 for quilting is shown. It should be noted that embodiments of the present disclosure are not limited to the particular configurations of quilting machine 100.

The term quilting machine 100 encompasses any device for stitching or embroidery of a textile 102. The term includes quilting machines 100 for stitching together multiple layers, such as a filler layer between a top and bottom textile layer, as well as an embroidery machine.

Quilting machine 100 includes a main frame 104, a sewing machine 106, supporting frame 108 for supporting or retaining a textile, sewing head 110, a reciprocating needle 112, a motor 114, handles 116, brake handles 118, and brake pads 120 (not shown). The quilting machine 100 further includes a controller 122 operably connected to the sewing head 110 and an encoder 124. The controller 122 includes a computer processor 126 (not shown) and memory 128 (not shown) for storing computer program instructions. The computer program instructions when executed on the computer processor 126 allow for quilting machine 100 to perform the operations described below.

Controller 122 can also include a display and input, such as a touch screen, keyboard, key pad, and/or mouse. The controller 122 can be physically connected to the main frame 104 or the sewing machine 106. Alternatively, the controller 122 can be a stand-alone device, which communicates with the sewing machine 106 and the encoder 124 through a wired or wireless connection.

The term textile 102 encompasses any article of manufacture or fabric made by weaving, felting, knitting, crocheting, compressing natural or synthetic fibers. In one configuration, the textile 102 is a quilt.

Support frame 104 can be any variety of configurations, wherein the frame includes struts or supports for engaging components described herein. The frame can be made of any of a variety of materials or combinations such as metals, plastics, composites or wood.

Although the present disclosure is set forth in terms of a sewing machine 106 that is moved during stitching relative to a portion of the textile 102 (or work piece), it is understood that the textile 102 can be moved relative to a fixed sewing machine. Alternatively, both the sewing machine 106 and the textile 102 can be simultaneously moved.

The sewing machine 106 includes a sewing head 110, typically having a portion above the plane of a work piece retention area and a second portion below the plane of the work piece retention area, thereby providing for passage of a portion of the reciprocating needle 112 through the textile 102 and selectively engaging the passage of a length of thread through the textile 102. Exemplary embodiments of sewing machine 106 are moveable over the work piece retention area.

Support frame 104 provides the work piece retention area that retains the textile 102 or a portion of the textile relative to the main frame 108 and relative to the sewing machine 106. The support frame 104 includes the supply roll assembly 130 and the take up roll assembly 132.

Supply roll assembly 130 retains an initial length of textile wound about a supply roller 134. For systems employing a plurality of layers, such quilting having a liner, a filling and a top layer, there may be three supply rollers in the supply roll assembly 130. One of the supply rollers 134 is set such that a portion of the periphery defines a line in a plane of operation of the sewing machine 106.

Take up roller assembly 132 includes a bed roller 136 having a portion of the periphery generally coplanar with a portion of the periphery of the supply roller 134 and a take up roller 138 for winding the stitched textile 102.

Support frame 104 functions to retain a portion of the textile 102 (work piece) between the line of contact with one of the supply rollers 134 and the bed roller 136, if the take up roller 138 compensates for changing the diameter of the winding. The supply roll assembly 130 and the take up roll assembly 132 create a tension within the textile 102 between the two assemblies, thereby disposing the intermediate textile in a substantially planar orientation and defining a work piece retention area.

Encoder 124 encompasses any optical and mechanical sensors for sensing movement of the sewing machine 106 relative to the frame. The encoder 124 is operable to track and communicate with other elements of quilting machine 100. The encoder 124 is operably coupled to the controller 122 to communicate to controller 122 the data necessary to determine the direction, location, and speed of the sewing head 110 relative to the work piece.

In one exemplary embodiment, as the sewing machine 106 is moved relative to textile 102, the encoder 124 senses the direction and speed of the movement of the sewing machine 106. This movement, encoder 124 communicates to controller 122 and motor 118. Motor 118 controls the up and down speed of reciprocating needle 112. That is, the cycle frequency of the reciprocating needle 112 is driven by the motor 118. In order to provide uniform stitch length, as the velocity and distance moved of sewing machine 106 relative to the work piece is increased so is the speed of motor 118 and the up and down speed of reciprocating needle 112. Likewise, as the velocity and distance moved of sewing machine 106 is decreased so is the speed of motor 118 and the up and down speed of the reciprocating needle 112.

In one exemplary embodiment, sewing machine 106 is attached, sits on, or is placed on a railing system 107 (not shown). Exemplary embodiments of the railing system 107 allow sewing machine 106 to move throughout the extent of the work piece retention area. Exemplary embodiments of railing system 107 provide a set of rails that allow for movement in the x-axis direction and for movement in the y-axis direction along the work piece retention area. Exemplary railing systems 107 may include wheels 121 coupled to sewing machine 106 and rails affixed to main frame 104 that allow for movement of sewing machine 106 with wheels along the rails. In other exemplary embodiments, railing system 107 may simply include a plurality of sliding rails that allow for movement of sewing machine 106 throughout the work piece retention area. In yet another exemplary embodiment, railing system 107 need not include x-axis direction and y-axis direction rails, but simply includes a set of rails that are orthogonal to one another and allow for sewing machine 106 to move throughout the work piece retention area.

Exemplary embodiments of rails of railing system 107 can be substantially planar elongate, strip like members, wherein the wheels 121 of the carriage engage a longitude edge of the rail. Exemplary rails can be flat, such that manufacturing costs are substantially reduced relative to prior bent or multi-thickness rails.

Exemplary embodiments of handles 116 include one or more handles that are affixed or attached to sewing head 110. Handles 116 provide a means for a user to grip and move sewing machine 106 and therefore sewing head 110 in a desired direction through pushing or pulling of the handles 116. Handles 116 are positioned such that a user can grip or hold handles 116 and still be able to view the drop location of reciprocating needle 112 on textile 102 or possibly a display indicating a drop location of reciprocating needle 112 located adjacent to handles 116. In other words, handles 116 do not obstruct the view of the drop location of reciprocating needle 112. As shown in FIG. 1, handles 116 include two handles to be gripped by a user's hands. It should be appreciated that handles 116 may include one or more handles with corresponding grip portions.

FIG. 1 further depicts brake handles 118. Exemplary brake handles 118 are located, and affixed or attached to handles 116 such that a user is able to pull, push, or otherwise activate or release brake handles 118 while holding handles 116. Brake handles 118 are operably connected to brake pads 120 (not shown) such that when brake handles 118 are compressed or activated brake pads 120 are moved to the clamped or braking position. In one exemplary embodiment, one of the brake handles 118 is operably coupled to a first brake pad 120 affixed to the sewing head relative to a x-axis rail and able to selectively engage the x-axis rail, the first brake operable between an open position and a closed position. The open position allowing movement of the sewing head along the x-axis rail, the closed position substantially preventing movement of the sewing head along the x-axis rail. The other brake handle 118 is operably coupled to a second brake pad 120 affixed to the sewing head relative to a y-axis rail and able to selectively engage the y-axis rail, the second brake pad 120 operable between an open position and a closed position. The open position allowing movement of the sewing head along the y-axis rail, the closed position substantially preventing movement of the sewing head along the y-axis rail. In one configuration, the brake pads 120 are coupled to a caliper.

Brake pads 120 can be affixed to sewing machine 106 such that they are operable on the rails of railing system 107. In an alternative embodiment, brake pads 120 can be affixed to sewing machine 106 such that they are operable on the wheels that are also affixed to sewing machine 106 and interact with the rails of railing system 107.

When brake handles 118 are released or not activated, brake pads 120 are moved to the opened or released position. Exemplary embodiments of brake handles 118 provide that each brake handle 118 is operably connected to a single brake pad 120. For example, the left brake handle 118 may be operably connected to brake pad 120 located on the x-axis rail of railing system 107, and the right brake handle 118 is operably connected to a brake pad 120 located on the y-axis rail of railing system 107. In this configuration, the user is able to select which axial direction (i.e., x-axis or y-axis) the user desires to allow or prevent movement of sewing machine 106. In another exemplary embodiment, each brake handle 118 is operably connected to each brake pad 120 such that operation of either brake handle 118 either individually or together activates both brake pads 120 to the clamping position and thus prevents movement of sewing machine 106 in any direction relative to the work piece.

Exemplary embodiments of brake handles 118 include mechanical means such as a lever coupled to a wire or wiring which when pulled or activated by a user causes brake pads 120 to move to the clamped position. In another exemplary embodiment, brake handles 118 include electronic or touch sensitive/panel means which through electrical wiring or computer signals activate brake pads 120 to the clamped or open position. Brake handles 118 can be operably connected to the brakes, such as brake pads 120 through wired or wireless means.

In a further exemplary embodiment, quilting machine 100 through controller 122 includes a processor and a memory storing computer program instructions, which when executed by the processor cause the processor to stitch in a predetermined manner and activates brake pads 120 at certain instances during the stitching process. For example, a user may control the stitching and movement of sewing machine 106 through the use of a preprogrammed stitching pattern stored as computer program instructions in the memory. When the program is selected, sewing machine 106 will stitch the preprogrammed stitching pattern and will at select moments during the stitching activate and release brake pads 120 in accordance to the required movement of the sewing machine 106. In another example, a user may control the stitching and movement of sewing machine 106 through the use of a remote control. In this embodiment, the user may selectively activate brake pads 120 through a remote control that operates sewing machine 106, reciprocating needle 112 and the movement of sewing machine 106 through the work piece retention area.

Referring to FIG. 2, shown is a perspective view of an exemplary brake system of a quilting machine suitable for use in practicing exemplary embodiments of this disclosure. FIG. 2 depicts a sewing machine 106, sewing head 110, handles 116, wire 119, and brake handles 118. As illustrated in FIG. 2, handles 116 are coupled to sewing head 110 of sewing machine 106. Further, brake handles 118 are adjacent or proximate to the handles 116 such that a user can manipulate the brakes while viewing stitching or the drop location of reciprocating needle 112 by the sewing head 110 in the work piece retention area. Handles 116 may include a cushion grip or other grip known in the art to allow a user to more comfortably grip handles 116. Affixed to handles 116 are brake handles 118 for stopping or braking the movement of sewing machine 106 over the work piece retention area. As depicted, brake handles 118 are in the open, released, or non-braking position. Exemplary embodiments of brake handles 118 provide that brake handles 118 when not in use are maintained in the open, released, or non-braking position. In other exemplary embodiments brake handles 118, when not in use, are maintained in the closed or braking position. Brake handles 118, as shown in FIG. 2, may be moved to the closed or braking position by a user by pulling brake handles 118 toward handles 116.

FIG. 2 also depicts wire 119, which is coupled to brake handle 118. Wire 119 is also coupled to brake pads 120. Wire 119 is coupled such that movement of brake handles 118 from the open/non-braking position to the closed/braking position moves brake pads 120 from the open/non-braking position to the closed/clamping/braking position. Conversely, wire 119 is also coupled such that movement of brake handles 118 from the closed/braking position to the open/non-braking position moves brake pads from the closed/clamping/braking position to the open/non-braking position. Exemplary embodiments of wire 119 provide for a mechanical or electrical wires for mechanically or electrically communicating the movement of brake handles 118.

FIG. 1 further illustrates lock 140 located on brake handles 118. Exemplary embodiments of lock 140 provide a means for selectively locking brake handles 118 in the closed/clamping/braking position. For example, a user may compress brake handles 118 or one of the two shown brake handles 118 into the closed/clamping/braking position and then desire to maintain brake handles 118 in the closed/clamping/braking position. Lock 140 may then be pushed, turned, or activated into the locked position such that brake handles 118 remain in the closed/clamping/braking position without the user having to manually compress brake handles 118. Lock 140 will then maintain brake handles 118 in the closed/clamping/braking position until the user disengages lock 140 into the unlocked position. Exemplary embodiments of lock 140 can remain in the locked or unlocked position without user interaction.

Referring to FIG. 3, presented is a close up view of a portion of an exemplary brake system of a quilting machine suitable for use in practicing exemplary embodiments of this disclosure. Shown in FIG. 3 is an exemplary rail 109 of railing system 107, brake pad 120, wheel 121, and clamp 123. As is evident, wheel 121 is affixed to sewing machine 106 such that wheel 121 can rotate freely on rail 109. Wheel 121 sits on and rotates on rail 109 such that wheel 121 can move along the extent of rail 109, which provides for movement throughout the work piece retention area. Rail 109 as shown in FIG. 3 extends along the y-axis of the work piece retention area. Exemplary embodiments of railing system 107 also include at least another rail 111 (not shown) parallel to rail 109 along the y-axis of the work piece retention area located on the opposite side of quilting machine 106 from rail 109. Exemplary embodiments of railing system 107 further include one or more rails 113 (not shown) located along the x-axis of the work piece retention area. Exemplary embodiments of quilting machine 106 also include wheels 121, clamps 123, and brake pads 120 operably located on or along rails 109 and one or more rails 113 such that quilting machine 106 can move throughout the work piece retention area in the x-axis direction or y-axis direction.

In the exemplary embodiment shown in FIG. 3, brake pad 120, when activated by a user, can operably compress, clamp, or brake on rail 109 thereby creating friction and thus slowing or stopping movement of quilting machine 106. In other exemplary embodiments brake pad 120 is located adjacent to wheel 121 and operable on wheel 121, such that brake pad 120 compresses, clamps, or brakes on wheel 121. In this exemplary embodiment, brake pad 120 slows or stops wheel 121 from rotating and thus slows or stops movement of quilting machine 106. Exemplary embodiments of brake pad 120 are able to be selectively activated, compressed, or braked to slow or stop movement of quilting machine 106 along railing system 107. In another exemplary embodiment, quilting machine 106 only includes a single brake pad 120 for one of the rails extending in the x-axis direction and a single brake pad 120 for one of the rails extending in the y-axis direction.

Clamp 123 is affixed to brake pad 120 and provides a user of quilting machine 106 with the ability to manually lock brake pad 120 in the clamped or braking position. As shown in FIG. 3, clamp 123 is in the unlocked position, but clamp 123 can be rotated, moved or activated such that brake pad 120 is maintained in the compressed, clamped, or braking position. Clamp 123 is able to maintain brake pad 120 in the braking position, thereby preventing movement of quilting machine 106 along rail 109 until the user puts clamp 123 into the unlocked, unclamped, or non-braking position. Exemplary embodiments of the present disclosure provide for one, more than one, or every brake pad 120 to include a clamp 123 such that a user can select specific brake pads 120 to place in the locked, compressed, or braking position with clamp 123.

Exemplary embodiments of clamp 123 include manual clamps as depicted in FIG. 3 and electronic or robotic mechanisms that allow clamp 123 to be selectively maintained in the braking position. Exemplary embodiments of clamp 123 allow a user to selectively place and maintain brake pads 120 in the locked, compressed, or braking position until the user desires to move clamp 123 into the unlocked or non-braking position.

Referring to FIG. 4, presented is a perspective view of another portion of an exemplary brake system of a quilting machine suitable for use in practicing exemplary embodiments of this disclosure. Shown in FIG. 4 are rail 109, rail 113, compressor 115, two wheels 121, and surface 117. Rail 113 extends along the x-axis through the work piece retention area and provides a means for quilting machine 106 to move in along the x-axis through the use of wheel 121. Exemplary embodiments of the present disclosure include a brake pad 120 (not shown) affixed to quilting machine 106 and operable on rail 113 to slow or stop movement of quilting machine 106 along rail 113.

Compressor 115 provides another alternative braking means for quilting machine 106. Exemplary embodiments of compressor 115 can selectively compress on surface 117 to substantially prevent quilting machine 106 from moving. Exemplary embodiments of compressor 115 include a screw mechanism that allows a user to turn compressor 115 in a clockwise or counterclockwise direction to move compressor 115 towards or away from surface 117 and is able to maintain its position. Exemplary embodiments of compressor 115 can thus either manually or electronically create friction with surface 117 such that movement of quilting machine in the x-axis direction is substantially prevented. It should be appreciated that while compressor 115 as depicted in FIG. 4 includes a screw mechanism to move it into the compressed position, exemplary embodiments of compressor 115 includes any type of mechanism that has the same functionality including springs and levers.

Referring to FIG. 5, presented is an exemplary logic flow diagram in accordance with a method, apparatus, and computer-readable medium for performing exemplary embodiments of this disclosure. Block 502 presents moving a sewing head in a first coordinate direction along a first coordinate rail and a second coordinate direction along a second coordinate rail, the first coordinate direction and the second coordinate direction being perpendicular to one another; and braking, by a first brake and a second brake, a movement of the sewing head, the first brake affixed to the sewing head relative to the first coordinate rail and able to selectively engage the first coordinate rail, the first brake operable between an open position and a closed position, the open position allowing movement of the sewing head along the first coordinate rail, the closed position substantially preventing movement of the sewing head along the first coordinate rail, the second brake affixed to the sewing head relative to the second coordinate rail and able to selectively engage the second coordinate rail, the second brake operable between an open position and a closed position, the open position allowing movement of the sewing head along the second coordinate rail, the closed position substantially preventing movement of the sewing head along the second coordinate rail.
